17 Claims.

If-he present invention relates to an inserting machine, andiparticularly` an inserting machine forum-stalling armature conductorsinto an armature.

ftis an obiect 'of-the invention to provide an apparatus of' this kindywhich will automatically feed, cut and inserta series of armatureconductors-lof propernumber'into various peripheralilly spaced slots inan arma-ture.

More particularly, it is `anobiect of the invention to provide amechanism of this kind having a feed, a cutting means and an armature4holder with interrelated operating means for the three-elements; so'that the feed supplies the proper amount of `wire and rod at the propertime ith-rough the cutting means, while the armature holding meansdisposes a proper slot for insertion 4of the end "of the wire into theslot, and at the proper time the cutting means cuts off the rod,whereafter the cutting means withdraws the :armature holding means,shifts to presenta new slot,. anda new feed cycle may begin.

A furthervobject is to .provide-.means for causing the mechanism tooperate to ll all of the slots of :a given armature and thereafter tostop.

vA further object is. to provide a mechanismof this hind that-may beoperated from the familiar :press head type of machine.

A `further object is to provide `an adjustable machine vthatmaybe usedlwith different sizes of armatures and different numbers of conductors.

A further object is the provi-sionY ofY a lcutting means that isIoperable by a rotating member to .effecticutting only byvrotationi inone direction.

Fig. 13 is a plan view of the presserplate` or ram adapter; and Y Fig.14 .is adiagrammatic view of the operating'parts ofthe machine.

The apparatus is conventionally mounted upon a base 2li that may be thebed of a press machine which has avertically reciprocating head 2l,preferably reciprocated up and down by a motor, shown .at M in Fig. 14,through conventional drivingmeans, as will be described in outlinehereafter.

On the bed is mounted a feed means l22 at the left in Figs. 1v and 2, acutting meansl 23 at the middle, -and an armature holding and rotatingImeans `24 at the right.

The feed means 22 is adapted to receive a wire Vor rod W from a suitablesource of supply., such as a coil'. The wire is conducted through*ypassages in itwosupports 25V and 26. Pairs `of feeding wheels 2l and1281 are disposed between the two supports 25 and 26, and additionalpairs` 2'9' and 30 are disposed tothe right or inwardly fromfthesupportZd The feed wheels 2l and 29 are driven together through gearing3I, 32, 33 in` conventional` fashion. These gears and their shafts. aresupported on a vertical wall 3d extending upwardiy from `the base. o i

The `shaft 35', with the` gear 3l, is operated through a conventional'ratchet Yclutch mechanism so -that the gears `:M -33 are driven inaforward directionr but not in a reverse direction. v A drivingmechanism, including gearing ."s'il and `38, operates the driving partof the clutch 36. `By this drive, as will; appear, `a series ofintermittent one-way feed movements are imparted to the lfeed wheels 27and 29. The drive is operated from the operating motor M for the wholemachine. This appears diagrammatically in Fig. 14, and' will' bedescribedhereafter.

rThe `wire passes kfrom the feeding means throughK atsupport l0 into thecutting means 23. This cutting means has a base W5 secured to the bed 2Uof the machine. The base 45 has an upstanding wall- 46 thereon extendingtransversely `of the bed'. vIt also has a second 'wall or post 41,spaced axial-ly from the wall 46k As will appear,

3 the post 41 is axiaiiy detached from the wail 45 for the interpositionof a rack member.

The wall 46 has a two-sized passage 50 therethrough to receive a drivewheel having a shape complementary with that of the opening 56, so thatthe wheel 5| is supported against end thrusts in one direction. Thewheel 5|, in turn, receives a sleeve 52 inserted along its axis. Thesleeve 52 has a head through which extends atta-ching means 53 (Fig. 3)for holding the sleeve within the wheel 5|. jection 54'extending to theright of the right face of the gear 5|, for purposes to be described.The sleeve has an axial opening therethrough whichis disposed in a linewith the opening of th'e wire support 40.

The left end of the wheel 5| projects beyond the wall '46 and is toothedat 55 to mesh with corresponding teeth on a rack 56, which is interposedbetween the wall 46 and the post 41 (Fig. 1), the space between thesemembers being of T-shape in cross section, to form a track for th'erack.

The rack 56 is vertically reciprocable within the foregoing space, andis contained therein by a back plate 58 that spans the space between thewall and the post 41. This rack is attached at its upper end to apresser plate or ram adapter 60 secured to the presser head 2|. Thus therack 56 will be reciprocated vertically in cycle and, as a consequence,the driving wheel 5| will be oscillated correspondingly.

The righ't hand face of the drive wheel 5| has two opposite studs 62 and63 projecting therefrom (Figs. 4, 6 and 12). The stud 62 receives oneend of a link 64, and the stud 63 receives one end of a link 65. Thelinks are complementary, and the link 64 is shown in Figs. 11 and 12.There it will be seen how the stud 62 is fastened into the face of thewheel 5|. The link 64 pivots freely about the stud, and at its free endhas another stud 66 receiving a cutter wheel 61. Similarly the link hasa stud 68 that carries a cutter wheel 69. The cutters are taperedoutwardly to provide a shearing edge properly disposed relative to themachine parts yet to be described.

Each link also carries a spring pressed plunger 10, the design of whichis clear from Fig l1.

These plungers are designed to spread the two links, as will appear, byan operation urging them to pivot about the studs 62 and 63.

It will be seen th'at the two cutters 61 and 69 have cylindricalportions 12 and 13, respectively. These cylindrical portions are adaptedto be engaged by a cam member on a cam ring 15. This cam member iscircular on its outside surface, and is held in position by a retainingring 16, there being suitable bolts 11 passing through the ring 16 andthe wall 46 for holding these parts together. The retaining ring has aninwardly extending flange 18 that extends over the face of the cam ring15. The cam ring may rotate within the confined space thus provided forholding it.

The cam ring 15 has an inwardly extending edge providing four camsurfaces 80, 8|, 82 and 83, successively joined by radial edges. Thesecam surfaces are adapted to engage the cylindrical parts 12 and 13 ofthe two cutters 61 and 69, which latter are constantly urged intoengagement with the cam edges by the plungers 10. In oth'er words, theplungers 10 tend always to separate the cutters.

The cam ring is permitted to rotate in one direction only, through aone-way clutch comprising a series of tapering slots 85, each containinga ball 86. In Figs. 4 and 6, this arrangement per- The sleeve 52 has asmaller pro. n

4 mits the cam ring 15 to rotate clockwise with re-h spect to theretaining ring 16, but it prevents counterclockwise rotation.

From the foregoing, it will be seen that when the rack 56 descends, thedriving wheel 5| will be rotated clockwise in Figs. 4 and 6. This willmove th'e links 64 and 65 clockwise also. After their respective cutterwheels `are 'theningengagement with a radial edge uponthe cam ring 15,this ring will also be rotated clockwise, a movement that is permittedby the clutch balls 86. When, however, the rack 56 starts ascending, thedriving Wheel 5| will rotate counterclockwise. This movement willdrawthe studs 62 and 13 counterclockwise. Any substantial movement of thecam ring 15`wil1fbe prevented by the clutch' balls 86, so that the linkswill be moved relative to the cam edges Bil-"83. This engagement of thecylindrical portions 12 and 13 upon the cam edges, along which theyroll, will force the cutter wheels inwardly to the position shown inFigs. 3 and 4, where their edges are in shearing relationship. As theend of the upward stroke of the rack 56l is reached, the cutters willdrop back of the radial edges on the cam ring 15 under the influence ofthe plungers 10, where they will be separated so that new wire may befed.

The armature holding means 24 includes runners provided on the bed 20 totrack a silde 9| for movement transversely of the bed. A support 92 issecured in upstanding relation uponv the slide 9|. This support holds acylinder 93 immovably, and this cylinder, in turn, has bearings 94 and95 to support a shaft 96. A screw 91 with a washer holds the shaft 96against endwisemovement in one direction. A cap 98 encloses the cylindertightly.

The other end of the shaft 92 has a shaft |00 threadedly attachedthereto. To this shaft is keyed a spacer wheel lill, which is clampedbetween one face of the support 92 and a shoulder on the shaft |00. Itis likewise keyed to the shaft for rotation therewith. Its feedingoperations will be described hereafter.

Also keyed to the shaft |00,` but removable therefrom, is a double discarrangement comprising two circular disc members |03 and |04. The member04 is smaller than the member |03, for a purpose to be described. Theouter end of the shaft |00 is threaded to receive a removable cap |05.An armature, shown in dotted lines at A, may be disposed over the shaft|00 upon removal of the cap |05, and retained thereon securely uponreturn of the cap and upon its being tightened into position.

The feed wheel |i| has ratchet teeth |08 about its edge. These areactuatedby the lfollowing ratchet mechanism. The operating plate 66extends axially to overlie this wheel-IUI. It is provided with a notch|09 (Figs. 8, 13)` opening toward the front of the machine to receive ascrew H0 that is threaded into a plunger urged upwardly by a spring 2.This plunger reciprocates within a confined space formed by a verticallydisposed angle member I3, the back end of which extends down against theback edge of the slide 9|. This member is duly secured to the slide. Athird side of the plunger space is formed by a vertically disposed wallmember |64, and a fourth side is formed `by a plate H5, the severalparts being Ytightly secured together to form the plunger container. Acover plate I6 is secured over the top of this container and is providedwith an opening through which the screw ||0 may pass.

The bail i3d isdrawnzforward, I bringing `with it .the .armature support=means 2'4'which isrnountediupon `the slideH, and to .whichthe bail is attached.Then'thecap 'H35 isunscrewed from the shaft Silit, `and an armature A,`usually comprising a seriesioflamlnations, is insertedover thefshaftagainst the-face ofthe disc Wfl. The shaft 'lzll has `a keycorresponding `to the key slotfinthe armature so that the armature isdisposed =`in proper position, and is held against rotation :relative tothe shaft. At the start, the key is in theftwelve oclockposition.Thefcaplll is `tlrereupon replaced rand `l tightened to `hold `thearmaturelinfplace. v

The armature rotating mechanism 2A is then moved backwardly until its'hits the `adjiustab'le stop screw illi. It will be seenfthatthe slot l'inthe plate |30 permitsrthescrew Mii to move into and out of the presserplate 6D, forthewithdrawal and replacement `of the armature rotatingmechanism. l

The screw Me is adjusted to stop the rotating `mechanism at a properpoint `"to dispose thewslot in `the nine oclockposition,-for ltheparticular diameter of armature, in axialalignment with the sleeve 52.`At this time, the press head 2i, the plate El) and the rack are all up.

The clutch is then --engaged by Closingthe switch |48. This starts`rotation of the shafts 15| and |52, and, after about one cycle, withdraws the pin M5 'from `the switch blade 1546, 'whereupon the switchcloses. The switch M8 may then be released 'This causes the feedmechanism 22 to project a predeterminedlength of vwire whichgoesintosthe armature slot,-then alignedwith the sleeve 52, and projectsonboth sides 1thereof. Thereduced diameter of thedisc |04 permitsthewire Vto-extendout thereover the proper distance.

AsLthe hea`d"2i descends, carrying the: rack 56 downwardly, nocuttinguaction occurs because .the driving wheelfl, thelinkszid and E5,andthe cam ring S15 are all moved clockwise, in Figs. 4 .and.6. Thefeedstops at the timezthe plunger 2| reaches the bottommfwits stroke.rllhe very last part of this stroke causes :the :plate .i60 to strikethe nut Hf'l' 'of the armature rotating ratchet `wheel mechanism,so thatthenal part of .the stroke displaces .the ratchet dog |22 the distanceof onetooth, or several teeth, depending uponthe angular distancebetween adjacent armatureslots. `Displacing the nut lil upwardlyincreases the distance of angular displacement.

As the plunger ascends, .the cam ring :15 is held against motion by itsball clutch, while the .driving `wheel 5i is rotated counterclockwise,

` nwhich drawsthe cylindrical parts 12 and i3V of the T byra connecting4rod and "Ib links 64 and 65 along .the inwardly sloping cam edges,and-causes the .two links to close the cute (ter wheels-together tocutqoi the wirethus disposed in the armature slot. This cutting actionoccurs between the ends of the upstroke, and 4further upwardtravelrthereaftercauses the `'Cylindrical parts 12 and 'I3 of the twocutter wheels to drop over a cam edge and be freed from cutting positionunder the influence of the plungers 10. A slight overtravel beyond thesaid radial edges of the cam does not return them to closed position.Thereupon, at the final part of the upstroke, the plate 60 strikes theupper nut ||8 on the screw |||l of the armature rotating means to liftthe same to its starting position, at the same time advancing thearmature the proper distance to dispose a new slot in position toreceive the subsequently inserted conductor. After a complete revolutionof the wheel during which all of the armature slots will have been lled,the pin |45 Will open the switch |41, to open the clutch |49 and stopthe mechanism.

It will be seen 'that overtravel of the cylindrical portions 12 and 13of the two cutters relative to the cam ring 15 is inconsequential,because a sub sequent downstroke will rotate the two links backwardlyuntil they strike the edges, which will then provide a starting positionfor the following upstroke.

The detent mechanism, comprising the wheel |32 and the spring pressedplunger |33, will re tain the armature rotating wheel |0| in theposition to which it is moved by the positive action of the plate 6|)against one or the other of the two nuts and ||8. The force of thespring ||2 is insufficient to overcome the detent mechanism.

It will be understood that the conventional feed mechanism 22 may beadjusted to vary the length of wire fed -per stroke. Different diametersof armature, and different angular spacings of the slots, areaccommodated as already described. Armatures of different axial thickness may be used by substitution of different backing discs |03 and |04,these discs being readily removable. Diierent armature shaft sizes maybe accommodated by different shaft extensions |00, these extensionsbeing readily removable. In case the teeth of the spacer ywheel |0| donot correspond to the angular spacing of the slots, differently toothedspacer wheels may be readily installed.

The removability of the sleeve 52 enables the cutting mechanism to beadapted to various sizes of wire conductors. The cutter Wheels arereadily accessible for servicing when the slide 9| is drawn forward.

The machine is easily synchronized, as the feed mechanism operatesthrough a clutch so that it may be adjusted relative to the rotatingmeans, and the cutters are easily synchronized by reaching in androtating the cutters backwardly against the one-way clutch.
